If it won't get below 50, first check the basics: it's level, the vents are clear, and the burner and flue are clean. On the N300/N302, temperature is set by a thermostat, not a thermistor. That's the Thermostat 636495, and it's in stock. If the thermostat is working and it still runs warm, the cooling unit may be getting weak. See our not cooling guide. The N300 is discontinued, and Norcold's replacement is the Norcold N4150. See our Norcold replacement guide.
